Relating to, resembling, or containing chyle (a milky bodily fluid produced during digestion).
From Latin 'chyl-' (from Greek 'chylos' meaning juice) plus the English adjective-forming suffix '-aceous' (meaning full of or pertaining to). Medical/biological terminology standardized in the 18th-19th centuries.
The suffix '-aceous' is a Latin-based English builder that shows up constantly in scientific words—'herbaceous,' 'cretaceous,' 'sagacious'—and it's like a superpower for scientists who can just snap it onto Latin roots to make new adjectives instantly!
